FitSegmentToPoints | Approximates points with a segment using selected outliers suppression method. Finding a locally optimal segment. Good enough when the number of outliers is small. |
|
FitSegmentToPoints_RANSAC | Approximates points with a segment using a RANSAC algorithm. Finds a well matching segments, but for handling outliers requires a distance threshold that may be difficult to set. |
|
FitSegmentToPoints_TheilSen | Approximates points with a segment using TheilSen algorithm, optionally with Siegel's improvement. Finds a well matching segment, ignoring up to 29.3% (TheilSen) or 50.0% (Siegel) outliers. Outliers do have some influence on accuracy. |
|
FitSegmentToPoints_LTE | Approximates points with a segment using Least Trimmed Error algorithm. Brute-force finding of a segment that best matches a subset of the input points. Very efficient against outliers, but possibly slow for bigger subsets. |
